Abstract

Patente de Invenção: "MéTODO E EQUIPAMENTO PARA TRANSMISSãO E CONSTRUçãO DE VETORES QUASE ORTOGONAIS". Um método de transmissão em um sistema de comunicações possuindo vetores de código ortogonais (10) para a transmissão de sinais de mensagem. O método inclui a formação de uma primeira matriz de vetores utilizando uma primeira série de deslocamentos cíclicos e a formação de uma segunda matriz de vetores utilizando uma segunda série de deslocamentos cíclicos. A primeira matriz de vetores é permutada para prover um código ortogonal e as operações.de permutação são determinadas. O método também inclui a aplicação das operações de permutação determinadas à segunda matriz para prover um vetor de código quase ortogonal (50). O vetor de código quase ortogonal (50) é aplicado a um sinal de mensagem para prover um sinal de mensagem codificado e o sinal de mensagem codificado é transmitido. A formação do primeiro vetor de matriz inclui deslocamentos cíclicos de uma seq³ência possuindo um polinómio característico.
